CM11 Themes: Add support for composed icons [1/2]

If an icon pack includes background, mask, and/or foreground
images and an icon is not included for a given app, an icon
will be generated using the background, mask and foreground.

Icon packs can include the following items into their
appfilter.xml
    <!-- Set deafult scale factor for the icons -->
    <scale factor="1.0" />

    <!-- Set back image for composed icons -->
    <iconback img="iconback" />

    <!-- Set the mask image for composed icons
         Original icon will be masked off using this mask -->
    <iconmask img="iconmask" />

    <!-- Set foreground image for composed icons -->
    <iconupon img="iconupon" />

Note: Mutliple iconback images can be used as follows
    <iconback img1="iconback1" img2="iconback2" img3="iconback3" />

listview: ensure active views are filled prior than scrap views

The internal Recycler#fillActiveViews should be called prior to add any view
to the scrapViews queue, so it can be use safely without detaching views
because out of sync.

hwui: Always enable the scissor while composing layer

Due to scissor optimization feature added in KK, scissor was disabled
all the time. Hence the undefined areas/region of textures are not
masking properly with GL_LINEAR filter mode.
